" the county of-Oswego arid'State of New -York, and BRUCE CLARK WHITE, aresident drawing glass cylinders and like'articles suchasare madeespecially for manufacturing:

:0 sheet-glass by opening the cylinders and. spreading the same flat ina familiar manner.

I A convenient manner of forming and drawing the cylinders is to di pinto a mass of molten glass a suitably-shaped bait to which the moltenglass fuses at its .marginand adheres, so that when the bait isdrawniipwardljy a hollow glass cylinder follows it, the.

cylin .er being divided between its produce 0 linder-sections of, anydesired 0 length, an the drawing of the lower or stub end of thecylinder being meanwhile continued as the cylinder-sectionsare dividedand removed therefrom. The invention consists-in the various mattershereinafter set forth and more particularly pointed out-in the appendedclaims. Among the principal o jects of our inven tion is to produce anapparatus for drawing glass cylinderswhich is so constructed that40-Wli61ijth6 cylinder islonce lifted or drawn frzom the'body of moltenglass. the bait may be parted from the c linder while the lower stub endof the cy inder remains continu. one or integral with the body, ofmolten glass, the drawing of the stub being continued and the cylinder,being parted or divided to pro duce sections of a desired length andwhich a when parted are removed to a suitable re- I posi'tory."ln'otherwords it is the object of :0 the invention to draw a continuouscylinder Specification of Letters Patent.

I from a mass of molten glass and'to sever cylinder-sectionstherefrom.

Another object of our invention is to pro vide means for continuouslyremoving the parted cylinder-sections to a suitably-located 5 5repository. v v

A further object of the invention is to provide means for sealing thestub end of thecylinder'i.e., that continuous with the molten glass andfor introducing air or other fluid into the cylinder below the sealduring-the drawing operation, whereby. a redetermined pressure may bemaintained in the cylinder.

A still further object or the invention is to 6 5 provide a combinedgripping and sealin de vice adapted to grip the upper end 0 thecylinder-stub an by which when lifting power is applied thereto thevdrawing operation may be effected and whereby the leakage of airthrough theupper end of the cyiinder is prevented while being thus drawnAfurther object is to provide a gripping device which will also serve asa means for removin the detached cylinder-sections. ,75

I A furt lier object of the invention is to provide a passage throughthe gripping device by which air or other'fluid may be forced into thecylinder as desired. c I

Another object of the invention is to provide means for'sustaining thecylinder-stub after a cylinder-section has been arted therefrom andwhileis aid detached cy inder- Zsection is-removed and until the upperend of the cylinder-stub is again grasped by the 8 5 grippingl device.

Anot er object of the invention isto ro-- vide two or more grippingdevices-or t eir e uivalentsoperating in connection with a 1i ting andremoving mechanism and adapt-' 0 ed to be brought successively intooperative relation to the cylinders and through the medium of which thecylinders are successively drawn and after being parted the ;.de-- ytachedcylin der-sections are carried to s. suit- 5 able repository,whereby saiddrawingand removin mechanism is continuously 0per:-' I atedto draw the cylinders from the'meltlngtank and to remove'the same. 1 i

In the operation of the machine illustrated a suitable length ofcylinder is first drawn upwardly by the bait and the drawing operationsuspended to permit the bait to be parted from the cylinder.

Referring now to the features of construc,

tion of the gripping devices F herein illustrated, F, Figs. 7, 8, and 9,designates a head which is fixed to the lower end of the air-pi e F. Tosaid head arepivoted four radia y-directed vertically-swinginggripping-arms F which areprovided at their outer ends Withverticalgrinping-flanges f,

The inner facesof said arms are lined with a suitable heat-insulating-material such asas- Att'ached to thelower end of the pipe F? below the head F is acircular horizontal disk, made of insulating material and of sufficientdiameter to close or seal the upper end of the cylinderj The margin ofsaid disk is clamped between the end of the cylinder and shoulders fon'the lower faces through the 'pipe F 'or otherwise will not escapetherefrom between said cylinder and gripping device. Said grippingarms.are adapted to be raised and lowered to detach the same from and attachthe same to the of said gripping devices is provided with a bracket Fwhich is fixed to the pipe F and to which is pivoted a lever F baidleveris connected at its inner end'with a sleeve F, which haslongitudinally-sliding engagement with the pipe FE Said sleeve F isconnected, by means of radially-directed links f with the gripping armsF near, the outer ends of the latter, as clearly shown in Figs. 7 and 8.When, the lever is raised, therefore, the gripping-flanges are movedtoward each other ina'manner to grip a cylinder surrounded thereby, andwhen said lever is depressed said gripping-flan es are moved outwardlyin a manner to re ease a contained cylinder. When the gri pingfianges fare forced inwardly against the upper end of a cylinderand the grippingdevice raised, the friction of the insulating facing of thegripping-flanges acts to hold the same in their gripping relation andprevents the cyl inder dropping away therefrom.

' In F1g. 11 is shown a slightly--modified form of the gripping device.

pfpg device is pivoted 1st abracket Ffiwhich is ed on the pipe F and thelever is loosely connected at its inner end with a sleeveF,corresponding in function to the sleeve F of the construction previouslydescribed. With the construction shown in Fig; 11 the gripping-flangesare moved toward the cylinder In this con struction the operating-leverF" of the grip- .when the lever F is swung downwardly and Y are releasedfrom a contained cylinder when said lever is swung upwardly. ln'this construction. the sealing and insulating disk f is omitted, and in lieuthereof :the grippingflanges and arms, the sleeve F, and the link thesleeve F and is clamped thereto by a clamping-ring If desired, thesealing-disk 7 may be employed with the construction last described. I

Two gripping devices areattached to the cable, one to each end thereof,so that when one of said devices is raised the other is low ered, and.vice versa. The said grippmgdevices and attached cylinders act,therefore, at certain times in the operation of the machine tocounterbalance each ,other,thereby reducing the power necessary tooperate the liftingcable.

After the bait B has been arted from the upper end of the first cylin erthe gripping devices are employed, the cylinder is further drawn, andthe upper end )arted therefrom to remove the detached cylinder anddeposit the same upon a suitable repository, such as a-car L. Saidgripping dGVNBS are operated to remove them to the repository, therotative head for this purpose swinging alternately from right to leftto bring one of the grip ing arting ofthe cylinders may be ef--alternately to lift the detached. cylinders and I shown,sai-d parting iseffected by means of a rotating cuttin -d1sk G, which is supported on aring G, W ich has rotative engagementwith an annular frame Gilocatedvertically above the forehearth and supported from the standardC by a bracket G", as shown. in Figs.

which engage vertical bearing-surfaces on the inner'surface of the frameG in the.

manner clearly shown in Figs- 1, 2, and 4. Said rollers extend under anannular horizontal flange on the upper margin of the annular frame,which prevents risim of the ring and cutter. The cutting-disk a isrotativelymounted in the inner end of a horizontally-swinging lever g,which latter i spivone. of the rollers g,

indicated in Figs. 1 and 2, and are prevented by suitable stops gjfromfalling below a certain level. When the bait is originally lowered intothe molten glass in the f)rehearth,-
